Line breaks in title, and including time of photography

Hi, I'm using the imageblock module of Gallery2 to show images in my blog. In order to make this as streamlined as possible I have a few questions.

First, I like to have the title displayed beneath the picture in the blog, but there is a problem with long titles displacing images severely. I am now using a solution I found on this forum, changing the title text field to a textarea. Although this solves the immediate problem, I guess this change will be lost on the next upgrade, and I would really like the title to be formatted with the same width as the image, with automatic line breaks. If anyone has any good suggestions I am eager to hear them. Perhaps an even better solution which keeps the title short would be to add an option of including the "description" field in addition to the title field, since the description field already allows line breaks. It something I can expect will be added to Gallery 2, or does anyone have any idea as to where (in which file) this modification can be made?

Second, adding the data option in the embedding command prints the date of the picture in below the title. I would really like to also include the time the picture was taken, but have not been able to find where this modification could be done. Does anyone know which file handles the date argument, and how would I go about adding an additional argument, datetime?

In eager anticipation of your suggestions,
Frank Olaf
